Explanation: If you are connecting via the String tab, here are the likely causes:

• If you have not specified a DSN, make sure to specify a DRIVER.

• If there is a space ahead of the DRIVER parameter, try removing it. Certain versions of SQL Anywhere have a problem with that.

• If you have specified a DSN, make sure it exists. Try using the DSN tab instead.

• Also check for the message "The specified DSN contains an architecture mismatch between the Driver and Application".
